video: av8100: Add Alternative Powerup Sequence
A HW issue in AV8100 can result in some HREF v60 and v70 boards
getting a bad +5V at HDMI output. Also FW download may be affected.
This patch provides a SW workaround for this HW issue.
The new powerup sequence is default behaviour. It can be switched
off in av8100_plat_data.
The HW issue may be resolved in later versions of AV8100 HW.
